How to distinguish turquoise from sub hard stone, how to identify turquoise?

Turquoise: Rock-like in the Platts classification table. Sub-Solid Stone:

Rocks in the Platts classification table. Pujian stone: Plats classification table, rock-like.

Extra-hard stone: Rock-like in the Platts classification table. Quorum No. YT1 6 YT1 9 Trench P22 Work Content:

Excavate the stone, break, trim, check the bottom, and the stone is transported.

1m away from the groove side. Trench chiseling: refers to the part with a bottom width of less than 7m below the 0-0 line.

The engineering quantity is calculated in cubic meters after the design size is increased and the allowable over-excavation amount is allowed. Allowable over-excavation thickness 1 general regulation of 20cm for rock-like rocks and 15cm for rock-like rocks. Trench drilling is divided into quota sub-items according to rock species, and corresponding quotas are taken according to the relevant geological drilling reports in the design documents.

Artificial liquidation of rocks refers to the liquidation of rocks on the face of artificial flat foundations or trenched pits, calculated as 50m3 per 100m2. The definitions of turquoise stone, sub-hard stone, pujian stone and extra-strong stone are defined in the quorum number yt1 8 yt1 1. Quorum No. YT1 0 YT1 3 Foundation P23 Work Content:

The stone is excavated, broken, and the bottom of the border inspection is repaired, and the stone is transported out of the groove 1m away. 【Interpretation】Foundation pit chiseling: refers to the design below the 00 line, its upper area is less than 20m2, and the calculation of its engineering quantity is the same as that of the trench engineering quantity.

The allowable over-excavation thickness is also increased. When the area of the upper mouth of the foundation pit is greater than 20m2, the trench excavation quota shall be fulfilled according to the trench excavation quota within 7m of the bottom width of the trench. When the bottom width is greater than 7m, the general excavation quota shall be fulfilled according to 1.

The quota does not include the transportation work after the excavation and blasting, and the engineering quantity should be designed according to the construction organization.

Calculated separately. The definitions of turquoise, sub-hard, solid and extra-hard stones are defined in the quorum number yt1 8 yt1 1. Quorum No. YT1 4 YT1 7 Trimming slope P24 Work content:

Trimming slopes and liquidating gravel. Trimming slope: refers to leveling on the side of the trench and removing gravel, the engineering unit is 100m3, and every 100m2 is calculated according to 30cm thickness.

Earthwork slope: for the maintenance of earthwork construction.

When the soil is stable, avoid collapse and ensure construction safety. When the cut exceeds 1 fixed depth or the fill exceeds 1 fixed height, the slope should be made. The slope of the earthwork slope is expressed by the ratio of the cut depth or fill height h to the width b of the bottom of the slope.

Slopes can be made into straight slopes, stepped slopes and polygonal slopes. The definitions of turquoise stone, sub-hard stone, pujian stone and extra-strong stone are defined in the quorum number yt1 8 yt1 1. See more answers

Sorry, I don't know how to tell the difference between turquoise and sub-hard, but I can provide some information about turquoise. Turquoise is a rock-like type in the Platts classification table.

Turquoise is a common gemstone of the oak yard and is prized for its natural color and texture. However, there are also some unscrupulous merchants or fraud rings in the market who will deceive consumers by disguising items similar to stones or chemical compounds as real turquoise. Therefore, you need to be cautious when buying turquoise and need to know how to identify pine age like auspicious stone.

Here are some ways to identify turquoise:

1.Observed Color: Turquoise typically exhibits natural colors such as blue, green, brown, gray, and yellow. If the color of the turquoise is too bright or unnatural, it may be a dyed synthetic turquoise, which needs to be paid attention to.

2.Observe the texture: Turquoise has distinct textures and streaks, which is one of its characteristics. If you see a stone with a flat surface and no texture or regular patterns, then it is most likely not a true turquoise.

3.Learn about geometric fancy: Turquoise is usually carved into various shapes such as oval, round, square, rectangular, etc. If the turquoise you see is a regular shape, then it may be a machine-made replica and not a true natural turquoise.

4.Luster: Turquoise is bright, clear or translucent, and this luster allows the inside of the turquoise to shine. If the turquoise looks dull and dull, then it may be a low-quality synthetic turquoise or other ordinary stone.

5.Contact test: Use warm and soapy water to gently wash the turquoise, then place it in your mouth and lick it gently.

If you feel that the surface of turquoise is cool, then it may be natural turquoise, because turquoise is a higher thermal conductivity. If the turquoise feels warm or doesn't feel at all, then it may be synthetic.

In summary, identifying turquoise requires a combination of many aspects, including color, texture, shape, luster and other peculiarities. If you're unsure about the identification of turquoise, it's best to consult a professional or find a trusted vendor.

1. Water soaking method.

Natural turquoise is very absorbent, and when you put it in clear water, different turquoise will react differently.

Porcelain pine has a higher density and a tight texture, and when you put it in clean water, it will not produce any reaction.

The soaking test can also detect the degree of turquoise porcelain, and the color of the turquoise after soaking in water has changed significantly, indicating that its porcelain degree is not high.

Second, the fire method.

Natural turquoise will turn black immediately after fire, but it will have no effect after being wiped off in time and washed off with water.

Turquoise is optimized to emit a pungent odor or plastic odor, which is a destructive method that most merchants don't let you test.

3. Color observation method.

The color of natural turquoise is relatively warm and moist, and the color is very natural; The fake turquoise color and luster will have artificial traces, and the color will look very uniform.

Fourth, look at the iron line.

This method is best suited for beginners and is simple and easy to do. Most of the natural turquoise will have a little iron wire, and the iron wire of natural turquoise is concave inside, and the texture is irregular, natural and casual.

After artificial treatment of fake turquoise, the iron wire is basically convex outward, and the thickness of the iron wire is very similar, it looks very stiff, and the distribution has no beauty.

5. Purple lamp identification method.

Natural turquoise does not react to violet light. And the optimized turquoise will also fluoresce significantly under fluorescence, which is why many veteran players always carry purple light torches.
